Many people with sleep apnea have what is referred to as “positional” sleep apnea. This refers to apnea episodes that occur when the patient is sleeping on their back, but not when sleeping on their side. It is estimated that 20% of people with moderate sleep apnea (15 to 30 events an hour) and nearly 50% of people with mild (less than 15 events per hour) have positional sleep apnea.

People often don’t make the connection between their loud snoring at night and their complaints of tiredness during the day. According to Samuel Krachman, D. O., professor of medicine and director of the Sleep Disorders Center at Temple University School of Medicine and Hospital, “They think that they’re just tired, not getting enough sleep or just working too hard. But in reality, it’s related to the sleep apnea.”

The new alternative is called Zzoma. The Zzoma, created by former Temple Fellow Joseph G. Crocetti, is a device which is worn around the chest like a belt, with a firm foam pad wrapped in canvas to keep the patient from rolling onto their backs.

Dr. Krachman says that they have been studying the use of the Zzoma in treating patients with mild to moderate sleep apnea and have found that the Zzoma is less obtrusive and easier to use than a CPAP.

“Although CPAP is very effective, the best studies have shown it’s only used correctly 50 percent of the time,” says Dr. Krachman. “That leaves many diagnosed with sleep apnea but not treated.”

The research, conducted by a team from Mansoura University in Egypt, evaluated a nonsurgical procedure that involves injecting a sclerosing, or hardening agent into the upper palate. The procedure is called snoreplasty.

34 participants with simple snoring were included in the study. Of the 34 study participants, 32 reported significant improvements in their snoring. On average they received 1.8 injections. In addition, the patients reported no significant side effects.

Snoring can result from many conditions including alcohol consumption, age, being overweight, having a cold, the flu or allergies. There are certain medications that can increase the likelihood of snoring.

More serious snoring issues can be related to sleep apnea, a condition where the breathing stops repeatedly during sleep.

The Egyptian study only dealt with those patients that had simple snoring involving issues with the soft palate and not with snoring due to tongue or nasal problems.

The researchers concluded that injection snoreplasty is a simple, safe, low cost and effective office treatment for simple snoring.

The teams findings were presented at the American College of Chest Physicians conference being held in Philadelphia, PA.

Statistics show that only 1 out of 5 people with diagnosed obstructive sleep apnea experiences daytime sleepiness. This means that a large number of people are unaware on their condition and the negative effects on their health.

Dr. Malcolm Kohler, of the Oxford Centre for Respiratory Medicine, and a team of researchers conducted a controlled, cross-sectional study to determine the differences in arterial stiffness, endothelial function and blood pressure in 64 people with minimally symptomatic OSA and compared these to 64 people without sleep apnea.

The endothelium is the thin layer of cells that line the interior surface of blood vessels. One of its functions is to regulate blood pressure.

“In our study, the augmentation index, a measure of central arterial stiffness that independently predicts cardiovascular events in high-risk populations, was significantly higher in patients with minimally symptomatic OSA compared to matched controls,” said Dr. Kohler. “We also found impaired endothelial function as indicated by decreased vascular reactivity of their arteries compared to control subjects without OSA.”

According to Dr. Kohler patients with even mild sleep apnea may benefit from use of a continuous positive airway pressure (CPAP) device.

This study will be published in the November issue of the American Journal of Respiratory and Critical Care Medicine.

According to the lead author of a new study, the drop in oxygen levels and inflammation associated with obstructive sleep apnea, over time, can lead to the death of brain cells. This “oxidative stress” causes architectural changes in the brain tissue related to learning and memory. The results of the study indicate that drinking 6 to 10 cups of green team can help offset that decline.

Dr. David Gozal, of the University of Louisville, and team of researchers studied the effects of green tea polyphenols (GTP), added to drinking water, on rats who were intermittently deprived of oxygen similar to the intermittent hypoxia (IH) effects of OSA on humans.

This study included 106 male rats that underwent intermittent oxygen depletion during a 12 hour night cycle for 14 days. Half of these were given the water treated with GTP, the other half were given plain drinking water.

The rats were then tested for markers of oxidative stress and inflammation, in addition to performance in learning and memory tasks.

The rats that were given the GTP water performed significantly better in the tests that those that received plain water. Also, the GTP supplemented rats showed 40% lower levels of markers of oxidative stress.

The antioxidants in green tea have been documented have been shown to improve many conditions, ranging from heart disease and high cholesterol to Alzheimer’s.

The study was published in the Journal of Respiratory and Critical Care Medicine.
